MAX40003ANS02+

Overview

The MAX40003ANS02+ is a single-channel analog comparator in a 4-bump WLP package. It operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 500nA. The device features an inverting input and an open-drain output. An internal reference voltage is preset at 200mV (typical). Input offset voltage is typically 0.5mV, and propagation delay is typically 9µs. It functions within a temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low power consumption preserves battery life in portable applications
• Tiny 0.73mm x 0.73mm footprint saves board space
• Internal factory-trimmed reference voltage eliminates external components
• High RF immunity through on-chip filtering

Applications

• Mobile devices
• Portable medical devices
• Notebook computers
• Electronic toys

Procurement Notes

Verify the specific suffix '02' confirms the 200mV internal reference setting. Confirm the 'ANS' designation matches the required 4-bump WLP package type. Ensure the '+T' tape-and-reel variant is selected if automated assembly is planned. Check for RoHS compliance status as indicated by the '+' suffix.

Selection Notes

Select this part when an inverting logic response is required relative to a fixed threshold. The open-drain output necessitates an external pull-up resistor. Consider alternative variants if push-pull outputs or non-inverting inputs are needed. Verify that the 200mV internal reference aligns with the target detection level.

Part Context

This component belongs to the MAX40002–MAX40005 nanoPower comparator family. These comparators are designed for compact, low-voltage, and low-current applications. The family includes both open-drain and push-pull output options across various packages.

Replacement Considerations

MAX40003ANS02+T is the tape-and-reel version of this component.
